Specification forming part of Design No. 122,388, dated January 2, 1872.

ingiormingpart ofthis specification, in which?-l Figure l is adetal sectional view of our improed hose-coupling taken through the line a: w, Fig. 2. Fig. 2 is an end View ofthe same..

Our invention consists in improving hoseeonplings, as hereinafter fully described and subsequently pointed out in the claim.

A represents the collar or receptacle for the end B of thehose.

end int-o which the hose B is inserted. The interiorvof the collar A, toward the rib a', is recessed to furnish space for the end of the hose to expanlinto When'the inner part C of the coupling lsf/screwed into place, and to form a v shoulder against which the end edge of the hose B may rest. The innersurface of the other end of the outer part or collar A has a screw-thread cut in it to ilt int'o the screw-thread cut in the outer surface of the inner or connect-ing part C. The outer surface of the inner or rbrwa-rd end of the part C is beveled off, as shown in Fig. l, so as `tolenter the end of the base more readily and expand it, pressing it against the inner surface of the collar A and clamping it between the outer surface of the said inner part C and the rib a'. The inner part C has a tongue or projection, c1, formed upon the inner surface The collar A is made with a rim or rib, a', around the inner surface ofthe I of its outer end fr a key-wrench to take hold of to enable the part C to be conveniently screwed in or out. D is a female nut to be screwed upon the nozzle of a hydrant, waterpipe, or street-washer to connect the hose with it. The outer endof the nut D has aninwardly-projectiug iiange, d', formed upon it to iit against au outwardly-projectin g iiange, c2, formed around the end of the inner part G, to swivel the said nut to the said part, so that the nut may be screwed on and oli without turning the part C or twisting the hose.

In attaching a nozzle tothe endof a hose the part C of the coupling may be formed as a solid part of the nozzle 5 or the nozzle may be screwed into the nut D. The outer surface of the collar A should be squared o' fo enable a wrench to take hold of said collar to hold it from turning while the inner part (l is being screwed in and out.- The outer surface ofthe nut D should valso be squared oh" to enable awrench to take hold of it to screw it on and off. This construction enables a hose to be conveniently mended by any one, should it b urst or cut, without its being necessary to take it 4 to a plumber, as must be done with the ordinary construction.

l Having. thus described our invention, we claim as new and desire to-secure byLetters Patentf A hose-coupling, formed of the collar A, expander .0, and swivel-nut D, each constructed and all applied together as and for the purpose specitied.
